NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. '7'73,032, datedOctober 25, 1904. Application filed December 26, 1903. Serial No.186,680- -(N0 model.)

To aZZ whmn it mag concern.-

Be it known that I, WILLIAM ROBINSON, a subject of the King of GreatBritain, residing at Kansas City, in the county of Wyandotte and Stateof Kansas, have invented certain new and useful 'ImprovementsinNon-Refillable Bottles, of which the following is a specification. I c

My invention relates to non-refillable bottles, and has for its objectto produce an efficient and reliable device of this character which canbe manufactured and sold cheaply.

To this end the invention consists in certain novel and peculiarfeatures of construction and combinations of parts, as hereinafterdescribed and vclaimed, and in order that it may be fully understoodreference is to be had to the accompanying drawings, in which Figure 1is a central longitudinal section taken on the line I I of Fig. 2. withthe bottle inverted land the parts of the attachment in the positionsthey occupy just previous to the opening of the trap-door to permit thecontents of the bottleto escape. Fig. 2 is a horizontal section taken onthe line II II of Fig. 1. Fig. 3 is a horizontal section taken on theline III III of Fig. 1. Fig. 4 is a horizontal section on the line IV IVof Fig. 1.- Fig. 5 is a horizontal section on the line VV of Fig. 1.Fig. 6 is a longitudinal section of a part of. a bottle-neck whenupright and showing a trap-door of modified form.' t

In the said drawings, 1 designates a bottle .of any suitable type,having its neck formed with an internal annular shoulder 2, disposedlength is slightlyless than the distance be:

tween gasket 5 and shoulder 3, the upper end or neck of said" casingbeing of slightly-reduced diameter and externally threaded, if

desired, as at 7. The bottom of the casing is in the form of aperforated or skeleton cone 10, which projects upwardly'into the casing,

so as to receive and guide therein a ball or weight 11 for a purposewhich hereinafter appears, which ball or weight may be of any suitableor preferred material and construction.

12 designates a push-rod which extends slidingly through the apex of theconical bottom and is provided at its lower end with a head 13 to bestruck by the ball 11 under conditions-hereinafter mentioned and havinga head 14 at its upper end to prevent its dislocation from the conicalbottom, said head 14: when the bottle is upright resting upon the apexof said bottom, as shown in Fig. 6. Just above the conical bottom thecasing is provided with a horizontal partition 15, having a largecentral perforation l6,which in the premanner on the-upper side of thepartition.

This partition and its gasket forms a seat for the trap-door 18, whichpreferably has an extension or arm 19 hinged to and between lugs 20,formed integral with the casing and its said partition by preference.The trap-door may carry the gasket 17 as shown in Fig. 6 instead ofhaving said gasket secured to the partition, and it is furthermoreprovided at its upper side with a marginal wall 2l,which increases inheight from hinge-arm 19 to the point diametrically opposite said armand forms, in effect, a pocket on theupper side of the trap-door for apurpose which hereinafter appears. Above the half of the trap-door fromwhich the hinge-arm projects, so as to completely cover the latter, is asemicircular guard 22, formed integral with or secured to the casing,the inner edge of said guard being bent upward, as at 23.

24: designates an internally threaded cap to screw down upon thethreaded neck of the casing, said cap beingof such diameter that thespring-catches 25 may pass into the neck of the bottle to a point belowshoulder 3, the upper ends of said spring-catches flaring outwardly fromthe cap, so as to snap under said shoulder after such passage, thesprings being obviously pressed flatly against the cap while passing theflaring surface 4:, as will be readily understood, and said catches areriveted, as shown at 26, or otherwise rigidly secured to the cap.

27 designates a substantially semicircular guard-partition for the cap,said partition being connected to the latter by the marginal flange 28.The partition is of such area and the flange 28 of such depth that theguard occupies a position about half-way between the top of the cap andpartition 22 and, like the latter, terminates in a bent edge 29,whichprojects in the opposite direction from the bent edge of partition 22.The top of the cap is provided with numerous fine perforations in thathalf overlying the partition 27, so that it will be practicallyimpossible for a person to introduce a wire through one of saidperforations and bend the same around partition 27, back between saidpartition and partition 22, and then downward to engage with and liftthe trap-door from its seat, so as to hold said trap-door unseated andintroduce a liquid into the bottle. It is understood that the trap isheld from accidentally opening by the spring 31 or its equivalent, saidspring projecting through the opening 16 and being secured at one end tothe trap-door and pressing at its opposite end against the normallyunder side of partition 15.

To assemble the parts in operative relation, the gasket 5 is firstforced down upon shoulder 2 and the ball or weight deposited in thebottle, and then the casing has the cap screwed thereon until thepartitions occupy the relative position explained, it being apparentthat partition 27 does not conflict with partition 22 in this action,because the bent end of the former never gets below the bent end of thelatter. The casing is now forced down into the bottle, its lower endcompressing gasket 5 slightly to permit the spring-catches to snap undershoulder 3, the resiliency of the gasket also pressing said springstightly against the shoulder, so as to hold the casing rigidly in thebottle, as will be readily understood. The usual cork (not shown) isthen inserted in the bottle, which is of course charged with the liquidbefore the non-refillable attachments are assembled, as explained. Topour out the contents of the bottle after the cork referred to has beenremoved, the bottle is simply inverted. \Vhen it contains a largequantity of the liquid, the weight of the latter will be sufficient toopen the trap-door, the liquid then passing between the partitions 22and 27 and out through the perforated top of the cap. By revers ng theposition of the bottle the trap-door resumes its seat, as will bereadily understood. WVhen the bottle contains only a small quantity ofliquid, it will cooperate with the ball or weight in unseating thetrapdoor, the momentum of the ball as it rolls downward and into theconical bottom of the casing against the push-rod being sufficient toforce the latter to unseat the trap-door, the weight obviously holdingthe trap-door open until as much of the contents have been poured off asis desired.

It will be impossible to recharge this bottle under pressure,as thepressure of liquid forced against the trap-door will cause the latter tobind more tightly upon its seat. It will furthermore be apparent thatliquid thus introduced will be concentrated largely in the pocket of thetrap-door,and thus act to more effectively hold the latter to its seat..It will also be clear that it will be impossible to charge the bottleby inverting it and submerging it in that position in liquid, as the aircontained in the bottle will prevent the entrance of the liquid, as willbe readily understood.

From the above description it will be apparent that I have produced anon-refillable bottle which embodies the features of advantageenumerated as desirable in the statement of invention, and which isobviously susceptible of modification without departing from theprinciple of construction involved.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is
